Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor joint device for covering joints of floors between left and right buildings such as a base-isolated building which has a large amount of movement and which is constructed through joints.

[0002]

2. Description of the Related Art Conventionally, this type of floor joint device has a pair of recesses formed on the floors of the left and right buildings on the side of the joint, and the bottoms of the pair of recesses. A pair of base rails fixed so as to cover, a joint plate that is slidably movable on both sides at substantially the center of the pair of base rails, and a joint plate that covers the joint portion, and the pair of base rails of the joint plate. A pair of cover plates attached to the pair of base rails slidably covering the located portion.

[0003]

The conventional floor joint device has no problem in a setting in which the left and right buildings have different swaying movements in the left and right directions. Since a large concave portion is generated, there is a drawback that the pair of cover plates in the concave portion is deformed when a load is applied. If the rigidity of the pair of cover plates is increased in order to eliminate such a defect, the pair of cover plates is deformed. There is a drawback that the plate becomes heavy and the joint plate does not slide smoothly.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
The joint plates can be smoothly slid even if the left and right buildings sway greatly in the left and right directions, and they can be deformed even if a load is applied to the pair of cover plates at the outer recessed portions on both ends of the joint plate. It is an object of the present invention to provide a floor joint device that can be efficiently blocked and used safely.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.
